Chris Kenworthy presents Charles Gauci's Demon Tube.
A wooden tube and a block are shown. The block is covered by the tube and a wand or pen is inserted through a hole which locks the block and tube together. The tube is then inverted. Amazingly the block penetrates the wand and falls from the tube.
This is an entirely new principle unlike anything you've ever seen before. The block is clearly shown to be at the bottom of the tube before the wand is inserted to secure it in place.
